“Public Health Wales can confirm that an individual resident in Wales is currently staying away from work and limiting contact with other people voluntarily following possible exposure to Ebola while visiting Western Africa,” a spokesman for PHW said.

“The individual does not have symptoms of Ebola and there are no cases of Ebola in Wales.”

The spokesman added: “We are alert to the possibility of Ebola cases in the UK given the outbreak in Sierra Leone, Liberia, and Guinea and we remain vigilant to unexplained illness in people who have travelled from the area.

“Processes have been developed to protect public health in the event that we are notified of any individual who may have been exposed to Ebola.”

Ebola is a severe acute viral illness often characterised by the sudden onset of fever, intense weakness, muscle pain, headache and sore throat. In its early stages its symptoms can often be confused with a cold or flu.

With Ebola, however, other symptoms emerge which include vomiting, diarrhoea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding.
